4-20 mA data logger with liquid crystal display

Temperature Technology manufacture and retails instruments for recording of temperature and related physical quantities. A part of the related physical quantities is milli-Amperes.

Many instruments, such as transducers, measure data, such as temperature, and send out a signal 4-20mA or 0-10V, which can be recorded and stored by our T-TEC A milli-Ampere  or T-TEC V Volt datalogger. 

The real benefit of the T-TEC A milli-Amp (mA) or T-TEC V volt data logger comes from the calibration program, TTCal. TTCal is included with the data logger and allows the user to scale the milli-Amp reading to any other reading they prefer, for example, pH.

Common measurements that are translated to 4-20mA or 0-10V by transducers:

  • turbidity
  • dissolved oxygen
  • pH
  • ppm
  • pressure
  • milli-Amperes
  • 0 to 100%
  • Humidity
  • Temperature
If you have instrumentation that outputs data in 4-20 mA or 0-10 V, T-TEC dataloggers and software can translate and record that data. You can leave the equipment while it is recording and later download the measurements to your PC or laptop for graphing, statistics, printouts and export to spreadsheets.

The T-TEC A and T-TEC V Data loggers come complete with input cable and a special scaling program where matching pair values  (from your transducer) are entered. The display on the T-TEC 7 logger will then show the scale in your specific units, and this scaling is also used in graphs and lists of measurements. The units on the display can be changed to 'none', V, mA, 2 or %.
